It is still my most played game this gen and I played it less than many of my casual friends.I hit 106 hours approx but I had friends hit 120 or more.The rumours I've heard on this game include the graphics being a big leap(not hard I know)and my favourite is that it will be 50 player (at least)or the large matches.
For me,as a tank driver the balance was destroyed with the over powered machine guns(they upped the power)and the impossible to defend against(in a tank)jet packs.
